PTFE Tube Stopper for all metal extruder - TEVO

thingiverse

I prefer working with metal components so I created this miniature part. This fix stops the PTFE tube from sliding back into the extruder gear during retraction. It's a quick 5-minute print, but still presents some challenges. Be sure you've calibrated your extruder and optimized flow settings to produce a successful print. Good luck with that!
